Free online decoder that expands compact UUID encodings back into full canonical UUID strings.

How it works
This tool decodes compact encodings back into 16-byte UUID values and formats them as UUID strings. It helps debug short IDs used in URLs.
Example
Input:
(short ID)

Output:
550e8400-e29b-41d4-a716-446655440000
FAQ
Why does decoding fail?
The short ID might not be UUID-based or might use a different alphabet/encoding. Ensure formats match.
Does this work for ULID or NanoID?
No. ULID and NanoID are different identifier formats and are not direct UUID encodings.
